Abstract

In this study, we proposed improvements based on actual measured data of a hybrid heat supply system that uses solar heat and ground heat as the heat sources of a restaurants complex in Honjo city, Saitama, Japan. Our evaluation from the actual monitoring measurements showed that the solar heat collection efficiency was 50–60%. The geothermal Heat Pump’s Coefficient of Performance decreased significantly in the summer. We propose to set the heat insulation and burial depth of the piping from the ground heat collection to the heat pump and recommends five units of 5 units of solar heat collectors as the most ideal scenario.
